It's seems that (the serious ) led growing industry is going (slowly )"warm whitey " ...

Check out :

6 x WW 3000 K (....I know why 3000 K LCW CQDP.EC ..... :-P ..No need for NW ....thus the blue 449 nm )
1 x Blue LD CQ7P (449 nm - 461 nm)
5 x Hyper Red: LH CP7P ( 644 nm - 666 nm...)
....
( Do not be misguided ...These lenses are for GREENHOUSE USE ...Not for average 1-3 m ( 3' - 9' ) high grow rooms/tents...

LEDiL Oy, a forerunner in the development in secondary LED optics,
introduces the new PETUNIA lens array designed specifically for
plant lighting fixtures. The current medium beam is ideal for use in
fixtures mounted a few meters above plant growth beds. The lowprofile
and densely-spaced PETUNIA array offers the ability to design
a compact fixture for use in crowded greenhouses. One of the biggest
advantages of using PETUNIA lenses and OSRAM OSLON® LEDs
is the tremendous reduction in energy cost and the ability to deliver
growing plants the light spectrum needed throughout their growth
cycle.

Edit :
3 contacts on PCB layout ....???

2 channels there ?
My guess is WW +Blue at one channel and the reds on the other .....
Which lights are those ?
..which are.JPG..????

PS: Hey Guod !! That looks a tad/bit/ ( a lot ? ) like yours !!! I mean whites +R/B combo ....
I'm telling you ..A champ ....
Although I'm a stuck-head ...I want to try only whites ....
Anyway ....It seems WW +Red 640/660 + blue 450 ,have to be working , just fine ...
( I mean it's used on large scale greenhouse plant cultivation ,there ..... )

6 x WW ( 3000 K ....I know why 3000 K LCW CQDP.EC .....
)
1 x Blue LD CQ7P (449 nm - 461 nm)
5 x Hyper Red: LH CP7P (4 x 644 nm -1 x 666 nm)

nearly the same as my passiv Modul... lol

Yeap...
But still I need the leds to be 35 pcs .....
No matter what ...


Wish I had graphic drawing skillz, but you do, so... again using an analog clock positions

the central cluster in the panel is 7 diodes.

When enlarging on this single cluster...

The adjacent 2 clusters total only 5 additional diodes because # 2 & 4, as well as #8 & 10, are serving double duty incorporated into the adjoining clusters.

when doing a bar, then the same goes for # 12 & 6 serving double duty for clusters above and below.

^ Did you notice the diodes in the led engine located in the middle of the header ARE Merkaba shape?

OH MY GOD!!!!

WHERE DID YOU FIND THAT ?

60€ for 14 Watt ....
Needs heatsink and ready for work ......

Can't rep you ,brother,right now !!! .......
But you deserve it,by all means !!!

30x50x9,5mm !!!!!

3 cm x 5 cm x 0.95 cm !!!
That is TINY !

How many of those can they fit on a heatsink 200 x 160 mm ,without having cooling issues ?
I wonder ......

Lenses have to go .....


One channel there ....

Guod !!!

This is way big .....

Now using these ,one can DIY ,his own grow panel ( a really high quality one !!!! )
MCPCB-driver -oslon ssl leds all in one package !!!
Needs a 24 V power supply & a heatsink and it is ready to go !!!

24 V , 6 Amps for the 140 Watts ....( 10 x 14 Watt )
600 € for ten of those .....



Oh ......
I wonder can they change the leds ?
( !!!!! I still want 10 x WW 2700 & 2 x NW 5000 K,on these babies !!!!! )

Who cares ..I can .....


Edit : Lens either have to go ,or changed with wider ones ....
These ones ,on-board-( OEM ) are going to burn the plants in no time ! )

Now ....
Let's design an "engine" with 12 pcs of leds ,specially for our plant !!!!

Not that this one is bad !!
But ..
Can it be better ?

Hmm....
A lot of testing here .....
Great little engines there ...
Really tiny and of high quality .......
And since they accept custom orders .......

.....
Also needed a ...
24 V ,6 A power supply ....
Or 2 x 24 V ,3 A ....

Oh ..I'm so excited with this ....
It will save me hours of work ....

How many Watts do you think those adhesive thermal pads can handle? It's big enough to stick multichip LED's to CPU coolers... One of those (plus asking the eBay seller to solder wires to the LED tabs, plus Wago 222's) would make LED spotlight construction virtually dummy proof.

You're not asking the right question ....These adhesive thermal pads can handle so many Watts ,until their temp rises to 155°C ....
No way you're going to have so many Watts ( of leds ) in such small area of 60 x 50 mm ...
So there's not such a issue of "How many Watts do you think those adhesive thermal pads can handle? " ....

They contact heat ...( and being dielectric ) .....
More than 155 C ,they probably soften and peel off ....
.....
multichip LED's to CPU coolers. ???

(You mean something like COBs ? )

It also costs 4.20 which is smthing to have in mind...:dunce:
Well I wasn't referring to the pads ,but to the led engines ..
About the pads ..Expensive or cheap ,you think ?
( 1 gr of epoxy from Fischer Electronik ,costs ~1 € ...An has less than 1 W/m.K conductivity ....Keep that in mind ... )

Oh! Didnt got that... :)

They are a bit expensive if you consider that 25gr of thermal paste are about the same price...(we agree here)

On the other hand i think the pads are not going to leave any airpockets in between...and that's a plus

And ofc it requires much less time to apply it on the surface than spreading paste all over...less messy also...

Appropriate for mass production , may i say...?:leaf:
